Title: Improved structure two-level ceiling lamp frame junction box
Inventor: WU WEN-CHANG
IPC: F21V21/03
Filed: 2002-01-03
Abstract: An improved structure two-level ceiling lamp frame junction box comprised of pendant fixtures having an upper peg-ended rod at their top ends that are press fitted into a ceiling mount and a lower plug-ended rod below that are socketed into a junction box. The junction box has a plurality of installed sockets, a retaining element is hinged to the two sides of each socket, and a flat spring is fastened to the top end of each socket to engage the lower plug-ended rods. A coil spring is respectively hooked onto notched nibs at the top ends of each pair of retaining elements, which control the extension and retraction of the coil spring. The upper peg-ended rod of each pendant fixture has a ball end that is pushed through a coupling spring an appropriate degree until the coupling spring rebounds and clips onto it, while the said lower plug-ended rod is tipped with a male fitting that is engaged by a snap-fit spring at the bottom face of the flat spring. As such, the upper peg-ended rods and the lower plug-ended rods are directly installed into the ceiling mount as well as the junction box and no additional fasteners or tools are required, thereby facilitating convenient assembly.

Abstract: It is presented here an invention which aims at providing a simple indicator  of direction for the exit of paper and of other materials in rolls of the respective materials installed as rotate reels. The invention is characteris ed by presenting a column formed by two successive alternate groups of words/phrases and arrows in horizontal lines, informing basically if the direction is correct (1) or incorrect (2), written upside down in relation t o each other. The group of words/phrases and arrows can be printed in the involucre of the roll, where many times there are specifications of the product, or can be affixed in the roll. The correct displacement direction a nd the incorrect displacement direction can be easily verified by the installer , because there is a natural tendency of people to read what it is written in the usual direction of writing and reading (with the letters with the head upward and from left to right (1 and 4)); and there is a natural difficulty of people to read what is written upside down and from the right to the left (2  and 3).

Title: Low loss and low polarization dependence waveguide variable optical attenuator
Inventor: SUN DE-GUI
IPC: H04B10/2507
Filed: 2002-05-28
Abstract: A waveguide variable optical attenuator using a pair of waveguide 3dB couplers configuration and having polarization dependence compensators is proposed in this invention. This pair of 3dB couplers forms a Mach-Zehnder interferometer where a pair of cross-state input port and output port is used. Because the access loss of a 3dB coupler is much less than that of a Y-junction, the system loss of the variable optical attenuator based on this invention is much less than that of the other typical structure of the variable optical attenuators based on a pair of Y-junctions. Generally, the polarization dependent loss is a vital issue for a variable optical attenuator with either the 3dB  couplers structure or the Y-junctions structure during it is being attenuated. In this invention, one or two polarization dependence compensators are made before each 3d8 coupler to correct any polarization dependent loss to the acceptable level. Therefore, the waveguide variable optical attenuator based on this invention can have low system loss and low polarization dependent loss.

Filed: 2002-07-11
Abstract: A production method for an aluminum alloy coated steel sheet. The aluminum alloy coated steel sheet is improved in appearance, corrosion resistance and workability resulting from dipping a base steel sheet into an aluminum alloy coating bath with a Si content of 5 to 15 parts by weight, a Cr content of 0.1 to 1.5 parts by weight and a Mg content of 0.01 to 3.0 parts by weight. Because of excellent workability, peeling of a coating layer and cracks of a coating film are reduced upon press working, thereby corrosion resistance being improved even after working. As a result, car mufflers, heat resistant home electric appliances, etc. having improved corrosion resistance can be produced.

Title: Removable bond for abrasive tool
Inventor: BULJAN SERGEJ-TOMISLAV
IPC: B24D3/00
Filed: 1997-08-27
Abstract: A bond for.a.metal single layer abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond.        Hence, the bond is particularly useful for the manufacture of large diameter, superabrasive metal single layer abrasive wheels employed in the construction industry.      The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method. of brazing the bond incorporates heating the bond composition to a temperature at most about 880°C to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900°C to dissolve the copper. The bond can also include an about 10-200 µm thick barrier layer of copper coating the cutting surface between the core and the bond composition.
